Furious Love Island viewers took to Twitter to blast the producers for messing with Dani's emotions.

One viewer said: "Appalling of producers to do that to Dani. Knowing it would upset her deeply.Why do that? Ratings are good enough. Also everyone knows Jack is loyal to her . Totally unnecessary of them to hurt someone for literally no reason. Disgraceful . Sick person thought that up"

"Actual emotional abuse on #loveisland. Not from the contestants but from the producers. Feel so sorry for Dani and Jack, especially since Jack has done nothing wrong," added another.

A third agreed: "Manipulating footage in order to deceive Dani to bring about an emotional response the way they did was intentional infliction of emotional distress and the #LoveIsland producers should be ashamed and whoever decided it was a good idea should be fired"
